Application led May 18, 1914. Serial No. 839,338.

To all L11/0m t may concern Be it known that I, CHARLES N. WATER-Ho'osn, a citizen of the United States, residing at the city of St.Louis, kState ofMissouri, have invented a certain new and usefulImprovement in Pliers, of which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same. f

This invention relates to pliers, and has for its main object to providea pair of pliers in which the crossed members comprising the same arepivotally connected together in a novel manner.

Another object is to provide a pair of pliers that is equipped with a.'screw-driver and a. Cotter pin puller, and lwhich is 'so designed thatthe two parts of same can be disconnected easily, `when it is desired touse one or the other of said tools.

Other objects and desirable features of my invention willy behereinafter pointed out.

Figure l of the drawings is a sideelevational view of a tool constructedin accordance with my invention.` Fig. 2 is a similar view showing thetwo members .of the tool arranged in a di'derent position. Fig. 3 is anend view of the tool shown in Fig. 1. Fig. l is a cross-sectionalviewtaken onr the line d-d of Fig. 2. Fig. 5 is an edge View of the toolshown in Fig. l. Fig. `6 is ak side` elevational view of one member ofthe tool.'

Fig. 7 is a side-elevational view of the other member of the tool; andFig.' 8 is a perspec` tive view ofthe pivot pin that connect's'the twomembers of the tool together.

Referring to the drawings which illus# trate thel preferred formvof myinvention', A and B designate the two. parts of the tool,

each of said parts,` consisting of` a member that has a curved handle 1and a jaw porf tion 2. The handle of the member' A is pro-` vided at itsouter end with a wedge-shaped portion that constitutes a screw-driverblade 3, and the handle of the member yB ris, -pro-k vided at'its outerend with a' pointed portion that constitutes a Cotter pin' puller 4.,"The members A and B are so designedk that when they are crossed theA`jaw portions 2 of same will lie directly opposite each other, andmeans are provided for pivotallyconnecting stitute a pair of pliers whenthey are comshaped that it can pass through the slot 6j in the member B,and thus permit said members to be separated only when said members arearranged in a. certain position. The portion 5b of the pivot pin 5 thatlies adjacent the head 5a is substantially oblong shaped in crosssection, and the narrowest part of said portion correspondsapproximately to the width of the narrowest portion of the slot 6 in themember B. Said slot is provided at its opposite ends withenlarged'portion 6 that correspond approximately to the diameter of thewidest part of the portion 5b, and when said portion lies in one or theother of the enlarged portions of the slot 6, as shown in full lines inFigs. land 2, the head on the pivot pin 5 will lap over the member B,and vthus prevent said member from beingdetached from the member A.

the, pivot pin 5, and then shift one of said,

members with relation to the other so as to arrange said portion 5b inthe enlarged portion y6a at the opposite endof the slot 6. In

other' words, the members A andAB are pivotally connected together by aslip joint connection, but, instead of permanently connecting said`members together, I have con-` nected said members together in such amanner that ythey can be completely detached `from each other, thusenabling the selected tool, either the screw-driver or the cotter` pinpuller, to be used independently of the other tool only. The pivot pin 5is permanently connected to the member A andthe portion of said inthat/passes through said member` is pre erably tapered or substantiallyfrusto-conical-shaped, as indicated at A nut 5d is arranged on areducedy threaded extension 5e of said pin and acts td draw` the taperedportion 5C into intimate engagement with the tapered walls of the iooCopies-of this patent be obte-ined lfor opening in Vthe'member A inwhich it is inserted.` By this construction, the pin 5 Yis held in anabsolutely rigid positionon the member A and there is no chance forlooseness or play between said pin and member.

rlhe end'portions of the jaws 2 of the members A and B are serrated at7, and/said ,i

jaws are provided with serrated recesses 8 that conform approximately tothe external f shape of a round rod orpipe when the members A and B arecombined, thus enabling the tool to be used for turning a pipe or' rod.Each of the jaws 2 is also provided adjacent its inner end with a.straight face 9, and when the members A and B are combined and separatedslightly, as shown in ufull lines in Fig. l, said straight faces 9 willlie parallel to eachother, so that they will bear evenly on oppositesides of the square portion on ,the valve lstem of an acetylene gastank, thus enabling the tool to be used as a key for turning on or orfthe valve of thetank, with# out liability of mashing or cuttingthe'sternof the valve` as usually occurs when anordinary` pair of pliersl is usedto turn the valve of a gas tank.

VIn addition to the devices previously mentioned, my improved tool isprovided with a wire cutter, which is kso designed that the jaws of thetool can be slipped over wire that is to be cut in practically the samemanner that shears areV used to cut wire. As

shown in Figs. 6 and 7, each of the members A and Bris providedwithV Aanotch 10, lo`` cated at the inner end ofthe straight face 9 on saidmember. When said membersare combined and arranged in theV manner shownin Fig. 1, the notches 10 alinew'ith' each other, as shown in Fig. 8,thus permittine a strand of wire to be inserted lin same.

If the handles 1 of said members are'pressed together,V after a pieceof' wire has' beeninserted in the notches loin said members', the'adjacent edges of said notches, which' are sharp,` will shear the wire'in two; f

A tool of the construction above' deseribed comprises all of thedevices' which an automobilisty generally uses, in keeping 'an anto#mobile in'repair and in adjustment. It com-A prises a pair of slipyjoint pliers whose jaws tre VSO square or hexagonal nut, or to turn arod orv pipe; it comprises a screw-driver and a "cotformed that they canbe used to turn a ter ypin puller which canvbe used independently ofeach other, owing to the fact that thetwo members or parts of the toolare' detachably connected together; it comprises two opposed straightfaces that lie parallel to each. other, vand which are spaced apart adistance equal to the diameter of the square portion 'on the valvestenrof `a gas tank,

thus enabling the tool to be used for turning a gas tank valve and itcomprisesa wirecutting device which is so arranged .that a strand ofwire can be cut easily by holding the tool in practically the samemanner that shears are used to cut wire.

v `Having thus described my invention, what I claim is:

' 1. A tool ofthe character described, comprising a pair of crossedmembers, and a pin secured to one of said members' that coen'- prises anirregularly-shaped head and a shank, said shank` havingoppositely-disposed flattened portions throughout its length, and themember to which the pin is secured being Yprovided with a taperedyopening that cooperates with a tapered portion on the shank of the pin,saidopening also having oppositely-disposed flat portions that coperatethe other of said vmembers having a perforation that alines with saidslot and whose opposite end walls are tapered longitudinally and curvedtransversely, and whose side' walls are ystraightl and parallel; and pinthat pass'esfthrough said slot and perforatin,- said pin having athreaded extension at one end and a head at its opposite end, said headbeing of substantially the same shape as said slot and being adapted tolie across ,the top of said slot when the tool is in oper# the shank ofsaid pinhavi-ng two straight parallel portions that extend tvepostion,

from the head'to' said threaded extension', the'A end yf said portionadjacent the head being adapted to cooperate with theintermediatereduced portion ofsaid slot, and the opposite end.eoperating with vthe straight side walls of said perforation, said'shank also being'tapered adjacent said threaded eX- tension forcoperation with the ,tapered end walls of-said perforation; and a nutthat coperates with said" extension" to prevent Vdlsp1acrnnenty or saidpin.
